the iWalk PowerFoot BiOMTM bionic lower leg system monitors and interprets the wearer’s environment through accelerometer and gyro sensors to dynamically adjust the feedback force profile through a network of three dsPIC33F Digital Signal Controllers from Microchip Technology. This session will show the sensors, batteries, motor, spring and communication paths used by the PowerFoot BiOM including a live demonstration of the technology.

With these premises in mind, Dr. Salter hypothesized that continuous passive motion should have the following effects on synovial joints: Enhance metabolic activity and joint nutrition, Stimulate pluripotential cells to differentiate into hyaline cartilage rather than fibrocartilage or bone, thereby leading to healing and regeneration of hyaline cartilage, and Accelerate healing of articular cartilage and periarticular structures, such as tendons and ligaments. * Salter RB, Hamilton HW, Wedge JH, et al.
